Metallurgical Equipment Component Plasma Hardening

  • V. A. Korotkov

Development of manual surface hardening by a plasma arc makes it possible to strengthen components not strengthened previously and to resolve many problems for increasing metallurgical equipment service life. In some instances, the service life of foundry crane gear wheels, cone crushers, crane rails, and various stamps, is increased by several factors.
